Greetings toms!
Long time reader, first time I've had to post a thread but I'm stumped. I'm constructing my 3rd build, and I've been slowly buying the components over the past 6 months or so. Finally got the money to finish it, and I can't get it to boot.

Specs:
Case: Coolermaster HAF 912 RC-912-KKN1
Power Supply: Corsair Enthusiast series TX 750w ATX/EPS 80 PLUS Bronze
MBoard: Gigabyte Z68X-UD3H-B3 LGA 1155
CPU: i7 3770 Quad-core 3.4 GHz LGA 1155
Memory: Corsair Vengeance 16GB (2x8GB) DDR3 1600MHz

So I put everything together, hooked everything up and ran my wiring nicely and tied it up all sexy (instead of breadboarding it first, stupid arrogant move) and it won't boot. Upon pushing the power button, everything fires up, LEDs on motherboard light up and the fans run. No beeping at all. And then after about 10-12 seconds it shuts off. Then after 5 seconds it starts back up, same thing happens, and it shuts off.

Feeling disgusted at my cockiness, I tore the whole thing back down and only had my Mboard, power supply, and processor (and case speaker of course). I checked the seating on my processor and double-checked the layer of thermal grease, both seem fine. So I fire it up again, and this time I get the steady "You didn't put any RAM in me" beeping. So I'm thinking that the stuff I have there is probably good, but when I put the RAM in, the same no-booting cycle starts again. So I shut it down, shuffle the RAM into the other slots, same thing. Try just one stick of RAM: same thing. Other stick: same thing.

So from what I read on here (since toms is my Build Bible) I'm thinking maybe the RAM is bad. I don't have any other guaranteed-good DDR3 around, so I pick up some more at Best Buy, planning to take it back once I can verify that the rest of the stuff is good.

Same thing.

I'm stuck. I don't know what to do. I have checked approximately 1000 times that the additional CPU power connector is plugged in, because it sounds like that's been the culprit in other builds. Can anyone help me figure out what I'm doing wrong, or what I have that is bad?

If you've read through all of this, I thank you so much for your time. You guys are truly awesome.

It's simply because your motherboard doens't support Ivy Bridge CPUs ( including the i7 3770 ) by default. A BIOS update is required for that. You need to put into your board a Sandy bridge i7( non extreme )/i5/i3/pentium/celeron CPU, use it to get into BIOS then update the motherboard's BIOS to its latest version before it can recognize your i7 3770.

So, since I don't already have a Sandy Bridge laying around, this is the cheapest one I could find:

Intel G540 CPU 2.50 GHZ 2M CACHE 2.5 2 LGA 1155 Processor (BX80623G540)

Will that suit my needs for this?

Awesome. I'll have it tomorrow, and I'll update the thread when I get it up and running. Thank you so much for your help Madn3ss795!
